Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a cleaning composition [11] containing an anionic surfactant formed from a basic amino acid.

It is already known that anionic surfactants containing basic amino acids as salts are used as detergents, and the following detergent compositions have been disclosed.

(1) A low-toxicity cleaning composition containing a basic amino acid salt of an organic sulfonic acid or an organic sulfuric acid ester (
41 Kaisho 50-6605).

(2) Contains a fatty acid base of basic amino acids as an active ingredient, it has suitable lathering and good cleaning power, is less toxic, is less irritating to the skin and eyes, and is biodegradable by microorganisms and can be absorbed in the human body. Cleaning agent M acid (% open vs. s
o-i6oI9mci issue).

(3) N-long chain acyl - N obtained by reacting 1 to 2 moles of basic amino acid with 1 mole of optically active acidic amino acid
-Transparent detergent based on long-chain acyl-optically active acidic amino acid-basic 2-anoic acid salts (JP-A-55-16009)
No. 0).

(4) An excellent low-temperature-stable cleansing composition containing a basic amino acid salt of N-long-chain acleglutaic acid and a specific amphoteric surfactant (% 1986-28297)
However, these cleaning agents have a unique odor that is thought to be derived from basic amino acids, making it difficult to commercialize them as cosmetics or toiletry products. Hitherto, as a general method of eliminating such raw material odors, masking methods using fragrances have been widely used in the cosmetics and toiletry product industries. However, it is difficult to mask the above-mentioned odor of Fi with the usual amount of fragrance added.

Although masking is possible to some extent, it is undesirable to incorporate an excessive amount of fragrance (a common sense amount), but excessive fragrance may cause skin irritation and impair the appearance and physical properties of the detergent composition.

The present inventors have conducted intensive studies on a method for eliminating the peculiar odor of anionic surfactants made from basic amino acid salts without masking them with excessive fragrance, and have already filed a patent application. It was discovered that a transparent solid detergent (%-No. 112997/1983) containing optically active acidic az-acid-basic amino acid salt with Shiku N-long chain acyl (No. 112997/1982) had no peculiar odor, and the present invention was completed. reached. .

That is, the present invention provides -COO-1-OS O;, -8O
; and containing an anionic surfactant formed into a salt (with a basic amino acid), wherein at least 20 wt urea is added to the basic amino acid cation of the anionic surfactant. Regarding odorless detergent compositions (excluding transparent solid detergents based on tomodashi N-long chain acyl-optically active acidic acid 2) acid-basic amino acid salts, which are characterized by: be.

The basic amino acid constituting the cation portion of the anionic surfactant containing a basic amino acid as a salt used in the present invention is selected from lysine, arginine, and ornithine. These basic amino acids may be either optically active or racemic. On the other hand, those forming the anionic part of an anionic surfactant having an active group selected from the group consisting of rz and -coo-1. be. The nine typical examples of these anion moieties are as follows. That is, fatty acids (8 to 8 carbon atoms)
22), chlorokylbenzenesulfonic acid (8 to 18 carbon atoms)
), alkanesulfone II (it prime number 14-22), alkenesulfonic acid (carbon number 14-22), higher alcohol sulfuric acid ester (carbon number 10-18), polydiethylene higher alcohol phosphate ester # (carbon IEIklO~
III), higher alcohol phosphate ester (carbon number 10
~18), alcohol ester of sulfonated higher fatty acid (carbon number 10-2G), sulfosuccinic acid ester of higher alcohol (carbon number 10-18), isethion shun high-
1 pho! -Ester (carbon number 10-1g), Ryosiltaurine (charcoal fiJ110-20), 11-sulfohigher alcohol acetate (charcoal fiillG-18), N-acylsarcosine (carbon number 1klO-20), N-acyl-N
-Methyl-β-alanine (10 to 20 carbon atoms), N-dyl-glutamic acid (10 to 2 carbon atoms), N-acylasparagine 11 (alo to 20 carbon atoms), and N-acyl peptide (10 to 20 carbon atoms). ), etc.

In the present invention, it is preferable that the anionic surfactant i/4Fi used as the basic afnoic acid salt has an equivalent ratio of anionic part to cationic part (basic amino acid) of 1:1; The form and purpose of use (may be changed depending on the shape and purpose of use.

For example, when the dianion S is an N-disol acidic amino acid, the basic i) acid is 1 to 1 to 1 mole of the anion.
2 mol is preferred.

In the method for producing an anionic surfactant using a basic af-noic acid as a salt in the present invention, volume A can be obtained by neutralizing the compound in the acid layer with a basic amino acid. In that case,
A common method is to add 0 ml of water, alcohol, etc., perform a neutralization reaction in the solvent, and then remove the solvent, but even if the compound in the acid layer is solid, if it has plasticity, It can also be produced by kneading with a basic amino acid using a roll or the like.

The amount of the anionic surfactant containing a basic amino acid as a salt used in the detergent composition of the present invention varies depending on the shape and purpose of use of the detergent composition, and is not specifically determined.

It is necessary to mix 20 wt or more of the urea salt used for the purpose of deodorization in the present invention, with respect to the cationic part (basic ζ) acid of the anionic surfactant whose salt is basic dianoic acid. be. For example, in the case of a cleaning agent containing lauric acid lysine salt 20f (molecular weight of lauric acid: 20G, 3, molecular weight of lysine: 14&ri), the weight of lysine in lauric acid lysine salt 20g is &4P (meaning -20X14/ (200,
3+146.2)P), so urea is 1.68F(
= &4
Below vomit, there is almost no deodorizing effect.

The cleaning composition of the present invention may contain other surfactants depending on the purpose, such as anionic surfactants such as sodium salts, potassium salts, and triethanolamine salts, amphoteric surfactants, and nonionic surfactants. May be used together. In addition, foaming enhancers, thickeners,
Auxiliary agents commonly used in detergent compositions such as binders, humectants, perfumes, colorants, and disinfectants may be appropriately blended.

The cleaning composition of the present invention can be prepared by appropriately selecting the types and amounts of an anionic surfactant containing a basic amino acid as a salt, urea, ice, and auxiliary agents. A cleansing agent in any shape can be obtained, such as a cream-like or transparent gel-like facial cleansing agent, a white opaque solid detergent, a transparent solid detergent, and the like. The manufacturing method of each of these shapes of cleaning agent may be according to the general manufacturing method of each shape.
